Considering a telescope with an objective lens with f1=932 mm and an eyepiece with f2=32 mm, at what distance could you resolve a dime (diameter=18.03 mm)? (Use the information from question 3 that the human eye can resolve about 1/60 of a degree, and answer in m.)
Homework Answers
Let the magnification of the telescope is m.
Let the size of the dime that the eye sees is d'.
Let the distance I can resolve a dime is R.
Now we know the angle
The distance
is 1805.242476 m.

A microscope has an objective lens with f = 16.22 mm and an eyepiece with f = 9.5 mm. With the length of the microscope's barrel set at 29.0 cm, the diameter of an erythrocyte's image subtends an angle of 1.43 mrad with the eye. If the final image distance is 29.0 cm from the eyepiece, what is the actual diameter of the erythrocyte?

Experiment 22: The Compound Microscope f2 Object 2 1 (Objective Lens)d L, (Eyepiece) d#150mm The Compound Microscope A compound microscope uses two lenses to provide greater magnification of near objects than is possible using a single lens as a magnifier. The setup is shown above. The objective lens, L1, functions as a projector. The object is placed just beyond the focal point of L1 so a real, magnified, inverted image is formed. The eyepiece, L2, functions as a magnifier. It...

This is a two part question. Part 1. To look closely at a small object, such as an insect or a crystal, you bring it close to your eye, making the subtended angle and the retinal image as large as possible. But your eye cannot focus sharply on objects that are closer than the near point, so the angular size of an object is greatest when it is placed at the near point (25 cm away from a “normal” eye)....
